EJDECTRICALLY-HJEATED COOKING UTENSIJL.

Patented May 23, 1222..

Application filed June 29, 1921. Serial No. tenses.

t ford and State of Ohio, have invented certain new and useful Improvements in Electrically-Heated Cooking Utensils, of WhlCh the following is a specification.

This invention relates to electrically heated cooking utensils, and is capable of application particularly to a percolator of that type in which the coffee or other fluid is caused to flow upwardly through a central tube in the body and overflows into a holder for the granular cofiee, thence returning to the bottom of the pot for repeated circulation.

The object of the invention is to provide a novel structure improved particularly with respect to the means for forming and assembling the parts which enclose the heater element, said element beingv in the form of a coil or ring which is assembled between circular plates located in a hollow well produced at the bottom of the pot, said well being made by a drawing or spinnlng operation and shaped to support the heating element as well as the central c1rculation tube.

The novel features of the invention will be more fully apparent from the following description and the accompanying drawings in which Fig. 1 is a vertical section of a percolator provided with the improvements.

parts of the electric heating device.

Referring specifically to the drawings, 6

indicates the body of a percolator or the of the body. Fitting around and enclosing the well is a cup or casing 9 which may also be spun or pressed, the diameter of this cup being such that a spaceis formed between the same and the well. The cup V9 is mountt ed on a cross plate 10 in the hollow stand 11 of the pot, and a boss 12 in the bottom of the well seats against the bottom of the cup. These parts are held together by a bolt 13 which may be welded to the well and which extends through holes in the bot- Fig. 2 is a perspective view of the separated tom of the well and the bottom of the cup and the plate 10, the three parts being thus fastened together by the screw and the nut 14 thereon.

The shoulder 8 forms a support for the conical or inverted funnel shaped lower end 15 of the circulation tube 16 which extends to the upper part of the pot in a manner well known in such devices, and the lower edge of the conical part 15 is notched as indicated at 17 so that'fluid may enter the well where it-is heated and forced upwardly in circulation through the tube 16.

The heating element, the parts of which are clearly shown in Fig. 2, consists of an inner ring 18 of insulated material which fits closely around the well 7, an outer ring 19 also of insulated material which fits closely within the cup 9,and a heating element 20 fittin closely between said rings, said heating efiament preferably comprising a coil of wire indicated at 21 wound around a mica core or ring 22. Leads 23 connect the wire or resistance element to the connecting plug 24 to supply current to the heater.

Tn assembling the parts the heater element consisting of the rings 18 and 19 with the intervening resistance coil is slipped on to the well 7. The cup 9 and plate 10 are then put in place, and the nut 14: applied to the screw, thereby holding the parts together. And they can be readily removed by removing the nut. The plate 10 acts as a heat shield to prevent the heat from affecting any surface on which the pot may stand. The ease with which the parts may be assembled or removed is an important feature of the invention, as well as the fact that the body and well of the pot or vessel can be spun or drawn from a single piece of metal without-joints or crevices. Removal of the central tube 16 and cone 15 opens the top of the well so that it can be easily cleaned or rinsed out.

The invention is not limited to the special form shown but may be modified in various ways within the scope of the following claims.

I claim:

1. An electrically heated vessel having a well depending from the bottom thereof, a heating element surrounding said well and a cup enclosing said heating element.

2. An electrically heated percolator com Jim prising a body having a well depending In testimony whereof, I affix my signature from the bottom thereof and a shoulder at in presence of two witnesses.
